Air conditioning repair 

Household air conditioning often made of four species problem:
phenomenon a: air-conditioning output insufficient
judge:
1, and if high pressure table displayed normal pressure, and low voltage table displayed high pressure, description evaporator pressure regulator, and heat bypass valve, and into integrity flow valve fault or adjustable;
2, and if discharge air temperature high, and pressure table pressure indicates normal, and or high, low voltage slightly has increased, is expansion valve filter network blocked;
3, and if high pressure table indicates over normal pressure, Low pressure gauge indicating lower than normal pressure, receiver dryer and pipe freezes, the receiver dryer filter block;
4, if the pressure gauge indicating higher than normal pressure, might have too much moisture in the system. If the bubbles are found in the observation window, mixed with the air in the system.
II: air conditioning on and off
judge:
1, if the low pressure gauge indicates too high or too low, adjust the thermostat does not work, the thermostat failure;
2, if the low pressure gauge and pressure gauge indicates the pressure is too low, the system has moisture in, plug the hot gas bypass valve or vacuum integrity valves.
three: no air BACK PAGE
